1 Integrated Coastal Zone Management Unit 5: Problem tree analysis

2 2 Unit content 1.Identifying and ranking local coastal threats 2.Understanding different perceptions of threats 3.Problem trees and their use 4.Comparing different stakeholders’ problem trees Learning outcomes Upon completion of this unit, students will be able to 1.Justify and explain their perception of domestic coastal threats 2.Be aware that different stakeholders perceive different threats 3.Understand how a problem tree is constructed 4.Use problem trees to compare stakeholder views Introduction

3 3 Task: In your view, what are the most important threats to the coastal zone in this country? -based on your own knowledge, experience or memory -can be local, regional or national scale, but must be domestic coastal zone: not overseas Local coastal threats

4 4 Task: In your view, what are the most important threats to the coastal zone in this country? -based on your own knowledge, experience or memory -can be local, regional or national scale, but must be domestic coastal zone: not overseas Local coastal threats How do these perceived threats vary within the group and what are the implications? -Individual perceptions reflect our own experience -Priority threats reflect our individual assumptions about the environment

5 5 Task: In your view, what are the most important threats to the coastal zone in this country? -based on your own knowledge, experience or memory -can be local, regional or national scale, but must be domestic coastal zone: not overseas Perceptions of threats How do these perceived threats vary within the group and what are the implications? -Individual perceptions reflect our own experience -Priority threats reflect our individual assumptions about the environment Can we try and imagine how others see the coast? What would be the priority needs of a company wanting to establish an oil palm plantation? What would they want from coastal managers?

6 6 Small group work: Group 1: tourism operator Group 2: urban developer Group 3: conservation NGO What are the top three coastal problems of concern to each group? What does this tell us about the perceptions, needs and priorities of different stakeholder groups? Perceptions of threats

7 7 A method to identify cause and effect in environmental problems Problem trees

8 8 A method to identify cause and effect in environmental problems Problem trees The effects are the leaves and branches of the tree. The problem is the trunk of the tree. The causes of the problem are the roots of the tree.

9 9 Fishers’ perceptions of effects of declining fish abundance Problem trees What are the main effects of concern to local fishers? - produce a list DECLINING FISH ABUNDANCE

10 10 Problem trees DECLINING FISH ABUNDANCE EFFECTS Declining catches Greater fuel expense Inability to feed families Growing debts Lack of alternative occupations Inability to invest in fishing equipment Possible loss of fishing grounds Fishers’ perceptions of effects of declining fish abundance

11 11 Fishers’ perceptions of causes of declining fish abundance Problem trees What do fishers see as the main causes of declining fish abundance? - produce a list DECLINING FISH ABUNDANCE

12 12 Problem trees DECLINING FISH ABUNDANCE CAUSES Too many fishermen Outside fishermen Destructive fishing Possession of fishing technology (eg sonar) UNDERLYING CAUSES Local population growth Migration to coastal areas New overseas markets for fish Fishers’ perceptions of causes of declining fish abundance

13 13 Problem trees DECLINING FISH ABUNDANCE EFFECTS Declining catches Greater fuel expense Inability to feed families Growing debts Lack of alternative occupations Inability to invest in fishing equipment Possible loss of fishing grounds CAUSES Too many fishermen Outside fishermen Destructive fishing Possession of fishing technology (eg sonar) UNDERLYING CAUSES Local population growth Migration to coastal areas New overseas markets for fish Fishers’ perceptions of cause and effect of declining fish abundance

14 14 Comparing problem trees Small group task -you are an offshore oil and gas development company -your main problem is ‘A lack of information regarding offshore oil and gas deposits’ -Construct a problem tree -What are the causes of the problem -What are the effects of the problem Lack of information regarding offshore oil and gas deposits

15 15 Comparing problem trees Small group task -you are an offshore oil and gas development company -your main problem is ‘A lack of information regarding offshore oil and gas deposits’ -Construct a problem tree -What are the causes of the problem -What are the effects of the problem Lack of information regarding offshore oil and gas deposits The coastal manager has to try and combine all stakeholders’ perceived problems and their opinions on causes and effects Integrated coastal zone management involves conflict resolution and trade-offs in decision making
